PROBABILITY SEMINAR
TIME: 3:35 – 4:25 p.m.
ROOM: HBB 132
SPEAKER: Mr. Matt Turner
TITLE: “Infinitely divisible random measures on time and space:
Stochastic Integration. Part 1.”
ABSTRACT: This will be a two part talk introducing and characterizing stochastic
integration with respect to infinitely divisible random measures (IDRM) on time and space. In part 1, I will introduce infinitely divisible distributions, processes and random measures. Then, I will introduce stable random measures and provide an analog to the Ito isometry for stochastic integrals with respect to stable random measures. In part 2, I will characterize stochastic integration with respect to an arbitrary IDRM and apply these results to tempered stable random measures.

Tuesday, November 2

MATH ECOLOGY SEMINAR
TIME: 9:00-9:50 a.m.
ROOM: NIMBioS small conference room
SPEAKER: Thao Chau
TITLE: “Habitat Edge Effects”

Wednesday, November 3

ALGEBRA SEMINAR
TIME: 2:30 – 3:20 p.m.
ROOM: 1st Floor, Temple Court (Math Tutorial Center)
SPEAKER: Mr. Jon Gray
TITLE: “(Co/Bi/Hopf-) Algebras” II

ANALYSIS SEMINAR
TIME: 3:35 – 4:30 p.m.
ROOM: AC 113
SPEAKER: Professor Tim Ferguson, University of Michigan
TITLE: “Extremal Problems in Bergman Spaces and an Extension of Ryabykh's Theorem”
ABSTRACT: I will discuss linear extremal problems in the Bergman space A^p of the unit disc. After giving some introductory information about this problem, I will introduce a theorem of Ryabykh relating extremal problems in Bergman spaces to Hardy spaces. I will then discuss an extension of this theorem for the case where p is an even integer.

GEOMETRIC ANALYSIS SEMINAR (Optimal Transportation)
TIME: 4:30 – 5:30 p.m.
ROOM: Haslam Business Building, 102
SPEAKER: Professor Fernando Schwartz
TITLE: “Displacement interpolation and displacement convexity II
(Chapter 5 of Villani’s 2003 textbook)

Friday, November 6

MATHEMATICS COLLOQUIUM
TIME: 3:35-4:35 p.m.
ROOM: HBB 102
SPEAKER: Professor Dietmar Bisch, Vanderbilt University
TITLE: “Subfactors, bimodules and planarity”
ABSTRACT: A subfactor is a mathematical object with an extremely interesting representation theory. Every subfactor comes with a finite or infinite fusion category whose intertwiner spaces carry an action of Jones' planar operad. This gives rise to many surprising algebraic-combinatorial structures, including a new notion of free product found in joint work with Vaughan Jones. I will explain these concepts and present some examples. The talk will be accessible to non-experts.
